Think big thoughts but relish small pleasures.
«Life’s Little Instruction Book» by H. Jackson Brown, Jr.
In Japan, there were many stores in Tokyo and Kyoto that have these ball vending machines.
Each is about a particular topic or series or whatever and the gimmicks inside are often keychains or similar small elements.
You simply put in the required amount (usually 300-500 Yen, a few want 1000 Yen), turn a lever and get a ball with the gimmick inside.
While probably more for children, it was nevertheless fun to try them out. Got a few Peanuts (Snoopy) things. And compared to the also frequent «crane games», you at least get what you pay for.
Oh, and BTW, if you ever need to change 1000/5000/10000 Yen notes into 100 Yen coins (for bottle vending machines/laundromats), these places have machines that do that. After all, no one requires you to spend the coins there …
Overall, gimicky stuff, but fun.
